The FotodioX Canon EF Pro Lens Adapter with Built-In Iris Control for Fujifilm X-Mount Cameras is a high quality adapter that allows you to mount a Canon EF mount lens to a Fujifilm X-mount camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment of the lens to the adapter. Additionally, this adapter features a built-in iris for controlling the amount of light let into your camera.

Although the lens will fit physically, automatic lens control and functions will not operate correctly while using this adapter. You can utilize aperture priority mode in combination with stop-down metering for automatic exposure control on your camera.

Q: 1. I just received Fuji X-Pro2 with Fotodiox yesterday. I mounted the Fotodiox and then a 50mm lens. I was able to manually focus (focus peaking works well), but I can't get the shutter to fire--I press the shutter button but nothing happens. Is there a setting in the camera that I need to change? Or is it the Fotodiox?

A: With my X-T1 it works when the menu item for soot without lens is set to yes. I would think that the X-Pros has a similar item in the menu. It is necessary as there is no electronic connection to the camera so it does not know that there is a lens attached.

Q: 2. so, i can manually focus (not auto focus) and still see in the view finder when I have a sharp focus?

Q: 6. Will this adapter make my Canon EF 75-300mm f/4-5.6 III USM work on the Fuji X-T10? Thank you!

A: You will be able to mount your 75-300 on the X-T10 a.f.a.i.k, ( it fits all X-mount Fuji cameras ) but be aware that you will not be able to stop you lens down, and what's more - the built in iris mechanism in this adapter is of no use, as you will get a circular formed photo on your sensor as you decrease the opening.
